Decode the deal

Separate a real price advantage from countdowns, anchors and incomplete totals.

A deal is only useful after the exact product, ordinary comparable price, seller, restrictions, delivered total and remedy have all been checked.

This section routes five different decisions. Do not collapse them into one checklist: the evidence that settles one may not settle another. Do not repeat promotional claims as facts. Evaluate the exact comparable product, total delivered price, restrictions and time value.

Freeze the offer

Take a screenshot showing the exact item, reference price, deadline, seller and exclusions. This step supports every question in this section, but the linked focused answer supplies the narrower test.

The Hong Kong Consumer Council publishes practical online-shopping guidance. Customs and Excise explains unfair trade practices under the Trade Descriptions Ordinance, while payment disputes remain subject to the card issuer or platform's own rules.

Save the offer, product description, seller identity, checkout total, delivery promise, return terms, payment record and correspondence in one evidence folder before any page changes.

A .hk address, large follower count, padlock icon or high search position is not proof that a seller is local, solvent or trustworthy.
